Kernrechtsfrage
Whether Art. 11(5)(a) SKV lacks a sufficient legal basis and violates the legality principle.
Extrahierter Entscheid
The provision is sufficiently authorized by Art. 55(7)(b) SVG and remains within the delegated power; no violation of Art. 5(1) BV.
Extrahierte Begründung
Art. 55(7)(b) SVG empowers the Federal Council to regulate the procedure and evaluation of breath and blood tests. Art. 11(5)(a) SKV merely specifies how breath-test results are to be assessed, complements the statutory scheme, and does not create an impermissible evidentiary rule.
